You can eat whatever you want

Getting vitamin D through supplementation shows zero benefits. A study over a period of 5 years found supplementing with Vitamin D had no impact on cancer, heart disease, or stroke.

A number of researchers now argue that people with high vitamin D levels are healthy not because of the vitamin, but because they get plenty of exposure to the sun. Vitamin D is just a marker of that fact.

A dermatologist discovered our skin uses sunlight to make nitric oxide, a molecule in the body that dilates blood vessels and lowers blood pressure.

He exposed volunteers to the equivalent of 30 minutes of summer sunlight without sunscreen. The result? The nitric oxide levels in the volunteers went up, and their blood pressure lowered. Because of the connection of high blood pressure to heart disease and strokes, this discovery can prevent millions of deaths globally.

Eggs have a lot of cholesterol compared to other foods. Although cholesterol in the blood is strongly related to heart disease, eating cholesterol is weakly associated with raising the cholesterol levels in your blood.

Eggs have other heart-protecting properties and eating it probably won't harm your heart.

• A chain email in the 1990s was responsible for the false belief that antiperspirant was raising the risk of breast cancer. 
• When researchers found higher ratios of aluminum in the brains of Alzheimer's patients, aluminum in antiperspirant was suspect. But it seems aluminum in antiperspirant is hardly absorbed by your skin.
  
  

The “best” diet is a theme: an emphasis on vegetables, fruits, whole grains, beans, lentils, nuts, seeds, and plain water for thirst. 

That can be with or without seafood; with or without dairy; with or without eggs; with or without some meat; high or low in total fat.

The darker your skin the less likely you are to get sunburn or skin cancer. However, dermatologists recommend using sunscreen anyway.

Science has not found any serious threats to your health from using sunscreen.

The chemicals in sunscreen, oxybenzone and octinoxate, are dangerous to coral reefs, which is why Hawaii has banned them.

There aren't any effective alternatives to sunscreen besides avoiding the sun.

• If you are healthy, and have a modern balanced diet, taking multi-vitamins and high-dose antioxidants may shorten your life.
• There’s no evidence to support antioxidant supplements for primary or secondary prevention of diseases.
• Beta-carotene and vitamin E seem to increase mortality, and so may higher doses of vitamin A.
• Antioxidant supplements need to be considered as medicinal products and should undergo sufficient evaluation before marketing.
• The functions of minerals and vitamins are understood largely by their deficiency diseases so there’s no certainty what they all do or how they interact.
• Antioxidants soak up toxic, chemically-reactive by-products of metabolism called free radicals. These free radicals, left unchecked, can cause damage to DNA and may be linked to cancer.
• Your body's immune system fights infections by using free radicals to kill bugs. Several of the minerals and vitamins in excess can cause damage.

• Folic acid for the women thinking of having a baby and pregnant women up to week 12 of the pregnancy.
• Vitamin D for all pregnant and breastfeeding women, those aged six months to five years or over 65 and for people who are not exposed to much sun.
• Vitamins A, C and D supplementation are recommended for all children aged six months to four years, especially those not eating a varied diet.
• If they are prescribed to you for a medical condition.

Keto is more than just a diet. It is a cultural identity.

The Keto diet changes how adherents think about medicine and nutrition. With the fake news that dominates the news cycle, it's not surprising that keto went viral. It's anti-establishment.

The body can only store glucose to last a few days. If we don't eat carbs, the body finds other ways to fuel the body, like ketogenesis. In ketogenesis:

• The liver starts to break down fat from food and our body reserves. The useful energy source is called ketone bodies and can replace glucose as fuel when there's a glucose shortage.
• Once ketogenesis starts, the ketone levels rise.
• The body burns fat instead of the usual glucose.

1. Nutrigenomics focuses on how the food you eat interacts with your genes and how different nutrients affect how you feel, think, and behave.
2. DIY biology: Biohackers with education and experience in scientific fields share tips and techniques to help non-experts conduct structured experiments on themselves.
3. Grinder: Grinders seek to become “cyborgs” by optimizing their bodies with a combination of gadgets, chemical injections, implants etc.

• Some forms of biohacking may be safe. For example, taking certain supplements or making changes to your diet can be safe. Even some body mods, like RFID implants, may be safe when overseen by a medical professional.
• Some biohacking methodologies border on the unsafe or even illegal. DIY bio and grinder sometimes center around experiments that aren’t considered safe or ethical in research facilities.

You can't catch a cold from being cold.  A virus is responsible for contracting a cold. We become infected with viruses when we are in close quarters with other people infected with a virus.

Cracking joints do not cause arthritis. Research done found people who crack their joints are at the same risk of getting arthritis than those who don't.

Pills, superfoods, and other wellness habits do not boost our immunity as the 'symptoms' which we get when infected are in fact measures taken by our immune system to respond to the foreign pathogen.

Many allergies that people have are a misguided response from the immune system that treat harmless foreign bodies as harmful pathogens.

While over-the-counter medicines provide us with a so-called ‘relief’ by suppressing our fever, runny nose and other ‘symptoms’, these are in fact necessary for the body to get well. The symptoms we want to be stopped are not our enemy:

• The mucus is helping flush out the pathogen.
• The fever(heat) makes the body impalpable for it to survive and replicate.
• The body pain is actually the inflammatory chemicals in your veins, guiding the immune cells like an air traffic controller.
• The brain is provided with a signal to slow down and let the body recover.
